Abstract

The invention relates to a low-pressure plane cargo space fire experiment simulation device which comprises an experiment table body. The experiment table body is a sealed space and is provided with a door and an observation window. The inside of the experiment table body is provided with a simulated fire source, an electronic balance, a thermal couple probe string, a heat line air speed probe string and a smoke content measurement probe string. The experiment table body is connected with a ventilating system, a vacuum system and a smoke exhaust system, wherein the ventilating system, the vacuum system and the smoke exhaust system are connected with a measurement and control system. The simulation device is a full-size experiment table for comprehensively researching fire smoke motion rules, fire detection, fire extinguishing and the like in a limited space of a low-pressure plane cargo space, changes of pressure in the cargo space can be regulated, air flow in the cargo space in a normal-pressure state and a low-pressure state is evenly distributed, pressure dynamic balance in the combustion process of the fire source in the cargo space is maintained, and besides, the simulation device is convenient to operate, safe, reliable and low in manufacturing cost.

Description

technical field [0001] The invention relates to a fire experiment simulation device for a cargo compartment of a low-pressure aircraft. Background technique [0002] In recent years, my country's air transport industry has developed rapidly, and air cargo transport has become an important source of income growth for civil aircraft. The subsequent fire safety issues in cargo compartments have aroused widespread concern. [0003] The aircraft cargo compartment is a special restricted space for movement, and the movement of fire smoke is extremely complicated due to the different space structures and cargo arrangements. The fire in the cargo compartment has the characteristics of a fire in a general movement-confined space, but it is different from other movement-restricted spaces in that its scale in the length direction is much larger than that in the height and width directions, and except for one exit of the cargo compartment door , there are no other vents, so that the sm...
